  • 전자기록 환경을 맞이하여 필요한 기간 동안 장기적으로 전자기록을 보존하는 것은 시대적 화두로 부상하고 있다. 특히 전자기록이 지닌 본래의 기능적 속성 및 원래의 비트스트림을 유지하며 원래의 모습을 그대로 유지할 수 있는 방안은 전자기록의 장기보존을 위한 핵심 관건이 된다. 그동안 우리나라에서는 공공기록을 대상으로 마이그레이션 방식을 장기보존 전략으로 채택해 적용해 왔지만, 기능성 및 원래의 비트스트림을 원래 그대로 유지할 수 없다는 점에서 한계가 노정되어 왔다. 전자기록의 장기보존 전략으로서 에뮬레이션은 비트스트림의 변화 없이 전자기록의 원형을 그대로 재현할 수 있다는 점에서, 아울러 마이그레이션처럼 전자기록 유형별로 개별적인 전략을 적용할 필요 없이 일괄적인 보존전략을 구현할 수 있다는 점에서 상당한 강점을 지닌 보존전략이다. 특히 현재 우리나라 전자기록의 장기보존 포맷에서는 구현해 주지 못하는 전자기록의 기능적 구성요소를 재현해 줄 수 있다는 점에서, 현재 공공기관에 보유중인 전자기록 유형 조사를 기반으로 그 실현 방안을 연구할 필요가 있다. 이에 본고에서는 전자기록의 장기보존 전략으로서 에뮬레이션의 적용 방안을 모색하기 위한 기초 연구로 에뮬레이션에 관한 서구의 최신 연구 사례를 검토하고, 에뮬레이션의 타당성과 대상, 방법에 대한 구체적인 사례를 고찰하려고 한다. 이를 통해 에뮬레이션이 지닌 장단점과 더불어 국내 적용을 위한 시사점을 모색하고자 한다. 이를 위해 본고에서는 에뮬레이션의 개념과 함께 장기보존 전략으로서 에뮬레이션이 지닌 장단점을 분석한 다음, 에뮬레이션에 관한 서구의 최신 선진 사례로 CAMiLEON, KB, Planets, KEEP 프로젝트를 분석하였다. 이러한 분석을 기반으로 향후 우리나라 전자기록에 대한 시사점 및 적용 방향을 제시하고자 하였다.

  • New HPLC method was developed for determination of some flavonoids such as naringin, hesperidin, neohesperidin, rutin, quercitrin, naringenin, hesperetin and apigenin and their contents in citrus juice and citrus peel from citrus varieties Brown in Cheju. Detection was at 280nm and reverse phase ${\mu}$-Bondapak C-18 column was used. Water/methanol/acetic acid as the mobile phase was better than water/acetonitrile/acetic acid. Flavonoids were more stable in 20% n,n-dimethylformamide in methanol(20% DMF) than methanol and pH 12 adjusted by 1N-sodium hydroxide solution. Standard flavonoid solutions were injected three times consecutively and the reproduciability was 0.236 to 3.550%, Correlation coefficient of the calibration curve was 0.9946 to 0.9999. The exiraction efficiency of hesperidin from citrus peel was evaluated with different extraction method such as reflux, ultra-sonicating method, using three solvents (aqueous solutions with pH12 adjusted by 1N-sodium hydroxide, methanol and 20% DMF), respectively. The reflux for 4 hour in 20% DMF was the most efficient of the tested methods and solvents, and recovery percentage were 78.0∼130.0%. Flavonoids were determined in citrus juice. Naringin was 68.2mg/100$m\ell$ in Natsudaidai, Hesperidin were 85.6mg/100$m\ell$ in Sankyool and Neohesperidin was 25.3mg/100$m\ell$ in Dangyooja. Flavonoids were determined in citrus peel. Naringin was 110mg/g in Dangyooja, Hesperidin was 242mg/g in Hungjin and Neohesperidin was 87.9mg/g in Dangyooja.

  • 포장식품의 유통기한 표시기법에 대한 대구ㆍ경북지역 소비자 222명의 심리를 설문조사 방법을 통하여 분석한 결과 소비자들은 포장식품의 유통기한 표시가 매우 중요한 정보라고 생각하고 있었으나 불분명한 유통기한 표시에 매우 혼란스러워 하고 있었다. 유통기한의 중요성에 대한 인식은 식품의 부패성향이 클수록 높았다. 유통기한이 지난 제품에 대해 대부분의 소비자들이 식용을 꺼리고 있었으며 역시 부패성향이 클수록 높았다. 소비자들이 가장 선호하는 표시기법은 선도유지기한 또는 유효기한이었고 포장일자가 가장 낮았다. 인구통계학적 상관관계를 조사한 결과 나이가 어리고 여성의 경우 유통기한이 제품선택에 있어서 보다 중요한 요소로 작용하였다.

  • This study investigated the preservation status of wooden architectural heritages, designated as Chungcheongbuk-do designated heritage in Jecheon. The purpose of this paper is to find the damage cause and the preservation method of wooden architectural heritages. It was conducted using the research methods of the existing literature and field survey to compare a current status of wooden architectural heritages. The result are as followings. Firstly, it was found the problems of a break, a damage, etc. in the platform and the problems of a cracking, an exfoliation, a corrosion, a warp, etc. in the wall. And, it was found a cracking of the beam(梁) and a roof tile(瓦), a falling of Angto(仰土), a sagging roof, etc. in the roof. Secondly, the damage causes of wooden architectural heritages were mostly caused by the physical limitations of the materials. And, it was caused by a rainwater, a subsidence of ground settlement, a destruction of waterproof membrane, etc. Lastly, the repair methods are making a quicklime layer in the soil mound on a cracking and an exfoliation part, a resin treatment or strut operation on a corrosion part of column, etc.

  • Objectives : To provide the information of preservation method for herbal decoction, we evaluated the anti-inflammatory effects according to preservation temperature and period of Pyungwi-san (PWS, Ping wei-san) decoction. Methods : The anti-inflammatory activity of PWS was investigated by carrageenin-induced paw edema in SD rats. At 0 month, PWS extract was administrated 100, 300 and 1000 mg/kg/day orally for seven days prior to induction of edema. Edema was induced by subcutaneous injection of 1% carrageenin into the right hind paw. The paw volume was measured at 4 hr following carrageenin-induced paw edema in rats. At 6 and 12 months, PWS extracts according to preservation temperatures (room temperature, $4^{\circ}C$ and $-20^{\circ}C$) were administrated in rats and then carrageenin-induced paw edema volume was measured. Results : PWS showed inhibitory effect on carrageenin-induced paw edema in rats and the optimal dose was 1000 mg/kg/day at 0 month of storage. At 6 month of storage, PWS storaged at $4^{\circ}C$ and $-20^{\circ}C$ were inhibited paw edema but that storaged at room temperature was not reduced paw edema in rats. Conclusions : These results suggest that PWS decoction pouch has anti-inflammatory activities at both $4^{\circ}C$ and $-20^{\circ}C$ during 6 month storage.

  • The maintenance works for brick-structured buildings are a new field in Korea, and practical cases are yet inadequate so that such works may cause adverse effects of damaging the buildings after all. Therefore, this study has extracted a preservation technology believed to be most desirable in minimizing the damage to the original state of the buildings and preserving the value as the cultural assets through maintenance work details from 1986 to 2010 regarding brick-structured buildings designated as cultural properties. Firstly, a brick replacement method of using the brick used at the time of construction is efficient in replacement and repair of brick material for preserving value of cultural assets and minimizing damage of the original form. Secondly, use of lime mortar through material analysis is effective in repair of masonry joint and mortar but it is not used often due to high experimental cost. Finally, reinforcement of structure using a form for a building with severe damage is most efficient when considering additional problems. However, damage on the original form of a building can be minimized and value of a building can be preserved only when consideration on sufficient case analysis, materials to be used, and conditions of a building is supported.

  • In order to set the direction of providing facility for the utilization of castle heritage, as well as to establish the method for securing access and determine installation criteria in consideration of preservation environment, an analysis was carried out on the cases of having secured access for people with disabilities in England for the advanced utilization of castle heritage. As the result of the analysis, the planning factors of the facility for people with disabilities in England for the utilization of castle heritage were deduced as follows: 1) The plan for facility was focused on the disabled using wheelchairs and visually impaired persons, rather than on services for hearing-impaired persons and people with learning disability. 2) As for audience movement line plan, regular route was used for audience movement line to lead them in a single direction. 3) As for the provision of prior access information, 3 stepwise access grades were established for the facility information plan of heritage. 4) As for information service by disability type, models were provided; and complementary explanation was provided by using text, drawing, picture, video and voice. 5) Rest spaces were secured where audience could look out upon castle heritage. For the utilization of castle heritage, it is necessary to develop planning factors of the facility design for people with disabilities according to its characteristics.

  • 본 연구의 목적은 오대산 국립공원을 대상으로 수치표고모텔, 용도지구 및 토지피복분류도를 작성하여 경관특성을 파악하고, 가시권분석을 통해 시각적 경관관리방안을 제시하는 것이었다. 분석결과, 용도지구는 자연환경지구의 면적이 감소하고 자연보존지구가 상대적으로 확대되어 보전의 성격이 강화된 반면, 취락지구도 면적이 증가하여 개발 가능성이 증가하였다. 토지피복은 자연환경지구에서 농경지 및 도시지역의 증가가 나타났다. 가시권분석을 통해 가시중복도가 높게 나타난 지역은 대부분 자연보존지구였으며 산림지역이 대부분을 차지하였다. 그러나 일부지역은 자연환경지구 내에 포함되어 지속적인 경관관리가 요구되었다.
